I'm just learning about hugelkultur and I'd like to try making a bed for springtime. In the second, and subsequent years, how do you prepare the beds for planting in spring, since you can't really dig them or till them? They'll probably be covered with weeds.
Also, people talk about building up the beds a little more each year, but how do you do that? Do you take dirt from somewhere else and put on top? I just have a medium sized suburban yard, and buying dirt by the bag is expensive.
